Minimum wavelength of x ray
WebScience; Physics; Physics questions and answers (a) A certain medical machine emits x-rays with a minimum wavelength of 0.029 nm. One day, the machine has an electrical problem and the voltage applied to the x-ray tube decreases to 71% of its normal value. WebThe wavelength of this radiation determines the minimum size of features which can be formed on the substrate. A lithographic apparatus, which uses extreme ultraviolet (EUV) radiation, having a wavelength within the range 4-20 nm, for example 6.7 nm or 13.5 nm, may be used to form smaller features on a substrate than a lithographic apparatus which …

WebcheckCIF procedure. PURPOSE: To check that the ratio of _refine_ls_number_reflns and _refine_ls_number_parameters is acceptable. The ratio of reflections used in the refinement to refined parameters (the r/p ratio) is important for ensuring precise atomic and geometric parameters. Higher r/p ratios generally improve the precision.
